잠언 2:6의 Musar

For sin dulls a man's heart, causing to depart from him true knowledge and the spirit of wisdom which the Holy One, blessed be He, bestows to the pious, as written "for G-d grants wisdom" (Mishlei 2:6). Thus he is left animal-like and material, sunk in the coarseness of this world.

These things can only be evaluated by one of understanding heart and sound intellect since it is impossible to clarify all their endless details, and "G-d gives wisdom; from His mouth comes knowledge and understanding" (Mishlei 2:6).

However, that which can protect a person and save him from these detriments is trust in G-d. Namely, that a person casts his burden entirely upon G-d, knowing that it is certainly impossible for a man to lack what was designated for him, as our sages taught: "all of a person's sustenance [for the year] is fixed for him from Rosh Hashana [to Yom Kippur]" (Beitzah 16a). Likewise, they said: "no man can touch what was prepared for his fellow even to the extent of a hair's breadth" (Yomah 38b).
